But the logo on September 15th got stuck in our craw. It's Google spelled out in crop circles, and while we have to admit we're not *totally* up-to-date on our crop circle history, we thought there might be more to it than just a fun look-briefly-and-click-away logo.

And there is. Not long after the logo went up on the main page Google tweeted a set of coordinates (51.327629, -0.5616088, for those coordinate buffs at home). No matter that the coordinates were posted in the wee smalls; tweeters immediately rolled up their sleeves (if people on Twitter overnight are indeed wearing things with sleeves; we suspect negligees and tanks) and went to work.
